I would use a bar chart when I need to compare the quantities of something between different things. For example the population of different countries.I would use a histogram to compare the frequency of something with the same thing but different quantities. For example, the frequency of books borrowed at a library in different quantities.

Histograms are together but bar graphs are not. Also, histograms do not have word labels on the horizontal axis but have numbers compared to bar graphs that have word labels.

When do you use a bar chart and when would you use a histogram?I would use a bar chart when I am comparing different variables that do not go in sequence. I would use a histogram when I am comparing variables that and go in sequence.

The different bars in a bar graphs represent different things/labels while bars on a histogram represent the same things. The horizontal axis of a histogram are usually of numbers with the same interval while bar graphs can represent different things.

When do you use a bar chart and when would you use a histogram?

A bar chart would be used for comparing things of different subjects. A histogram would be used to show the changes.

Histograms are on the same horizontal axis/together but bar graphs are not. Also, histograms do not have word labels on the horizontal axis but have numbers compared to bar graphs that have word labels. Bar graphs can be horizontal/vertical.

When do you use a bar chart and when would you use a histogram?

I would use a bar chart when I am comparing different variables that do not go in sequence/difference/variable. I would use a histogram when I am comparing variables that and go in sequence.

What difference do you observe?The have gaps in between each bar. Each bar represents a different objects. The vertical axis of the histogram always represent the frequency. While the vertical axis of the bar graph represents the number of an object.

When do you use a bar chart and when would you use a histogram?I would use bar chart if i want to compare the quantity of an object and i would use if i want to find out the frequency of an object and the changes over a period of time.

Below are 2 examples of Bar Charts.Let's compare Histograms and Bar charts...What difference do you observe?Histograms have no gaps in between the bars but Bar Charts has gaps in between bars.When do you use a bar chart and when would you use a histogram?A histogram can be only used to show comparison of frequency of things that are of similar genre but bar graphs can be used to show comparison between different objects.

What Difference do you observe?~The vertical axis on a histogram has a arrow, unlike a bar graphWhen do you use a bar chart and when would you use a histogram?~I would use a histogram to show the past's frequency of a particular matter and I would use a bar chart to compare some things.PS This is Ishani

The vertical axis in a bar graph does not represent frequencies while a histogram always does. The different bars in the bar chart represents different subjects/labels while the bars of the histograms represent the same label.

What difference do you observe?Histograms do not have gaps between the bars while Bar Charts have gaps.When do you use a bar chart and when would you use a histogram?I would use a histogram to show a frequency of something while I would use a Bar Chart for comparison.

What difference do I observe?Histogram's Y axis represents frequency while a bar graphs Y axis could be used to represent type. I would use a histogram when I am comparing objects of the same type, group or category.I would use a bar graph when I am comparing objects of different groups.

1) All the 'bars' are not connected to each other as it is in histograms. The horizontal axis of bar charts represents the 'group' of different objects while the horizontal axis of histograms represents numbers/words in 1 group.

2) Bar chart is used when we want to interpret more than 1 group of object while histograms are used to compare objects within a single group.

Video Clips about Data Handling

This video clip, Statistics: Decisions Through Data shows how data (in the study of Statistics) has enabled mankind to make big and small decisions, that either impact the individuals or the bigger community.

This video about... There are more than 350 different commodities grown in California. In a state that provides approximately 15 percent of U.S. agricultural products, statistics are an important tool for agricultural economists to keep up with supply and demand. Let's hear how the statistics help farmers to make decisions!
